You’re sitting on the couch, maybe scrolling through your phone, and you feel that faint thump-thump in your chest. Or perhaps your Apple Watch just buzzed with a notification about your pulse. You start wondering. Is 72 beats per minute actually good? What if it's 58? Or 85? Honestly, the "normal" range is a bit of a moving target, and the standard advice you find on posters in a waiting room doesn't always tell the whole story.
A healthy resting heart rate is generally cited as being between 60 and 100 beats per minute (BPM). That’s the official line from the American Heart Association. But here’s the thing: a lot of cardiologists actually think that 100 is way too high for a resting state. If you’re sitting perfectly still and your heart is hammering away at 95 BPM, you might technically be in the "normal" zone, but your body is likely under some kind of stress.
Why 60 to 100 BPM is Kinda Misleading
The medical community uses that 60-100 range mostly as a diagnostic baseline to catch major issues like tachycardia (too fast) or bradycardia (too slow). But if we look at longevity and cardiovascular efficiency, the "sweet spot" usually sits much lower.
Recent large-scale studies, including data published in Open Heart, suggest that a resting heart rate at the higher end of the "normal" range—specifically above 80 BPM—is actually linked to a higher risk of cardiovascular disease and even all-cause mortality. It’s a bit of a wake-up call. Your heart is a pump with a finite number of strokes in its lifespan. If it’s working harder than it needs to while you’re just watching Netflix, that’s wear and tear you don't want.
Elite athletes are a totally different story. You'll hear about marathoners or pro cyclists like Miguel Induráin having resting heart rates in the 20s or 30s. For them, that's a healthy resting heart rate because their heart muscle is so incredibly efficient that it can move a massive volume of blood with a single, powerful contraction. For a regular person, a pulse of 38 might mean a trip to the ER for a pacemaker. Context is everything.

The Variables That Mess With Your Numbers
Your heart rate isn't a static number. It's more like a mood ring for your internal physiology.
- Stress and Cortisol: Even if you feel "fine," your subconscious might be chewing on a work deadline. That keeps your sympathetic nervous system—your "fight or flight" mode—engaged, which keeps the pulse elevated.
- Dehydration: When you’re low on fluids, your blood volume actually drops. To keep your blood pressure stable, your heart has to beat faster to move that smaller amount of blood around. It's basic physics.
- Temperature: If it's a humid summer day, your heart is working double time to pump blood to the surface of your skin to cool you down.
- Caffeine and Meds: That third espresso? It has a half-life. It’s still in your system hours later, nudging your BPM upward.
Understanding the "Lower is Better" Philosophy
Generally speaking, a lower resting heart rate indicates a stronger heart muscle and better cardiovascular fitness. Think of it like a car engine. A high-performance engine can cruise at 70 mph while barely revving, whereas a struggling engine has to redline just to keep up.
Dr. Valentín Fuster, a world-renowned cardiologist at Mount Sinai, often emphasizes that looking at trends over time is more important than a single reading. If your heart rate used to be 62 and now it's consistently 75, your body is telling you something changed. Maybe it's lack of sleep. Maybe it's chronic inflammation. Or maybe you've just been skipping the gym.
How to Properly Measure Your Resting Heart Rate
Don't just look at your watch after walking from the kitchen. That’s not a true resting rate.

To get a real number, you need to measure it first thing in the morning. Before you get out of bed. Before you check your emails and get annoyed by a message from your boss. Sit or lie quietly for five minutes. Place two fingers on your wrist (the radial artery) or the side of your neck (carotid artery). Count the beats for 30 seconds and double it.
Do this for three mornings in a row. Take the average. That is your baseline healthy resting heart rate.
When Should You Actually Worry?
If you are consistently seeing numbers above 100, that’s tachycardia. You should see a doctor. It could be thyroid issues, anemia, or an electrical problem in the heart.
Conversely, if you aren't an athlete and your heart rate is consistently below 50—and you feel dizzy, fatigued, or short of breath—that's a red flag for bradycardia. If you feel fine, it might just be your genetics, but it’s always worth a mention at your next physical.

Real-World Ways to Lower a High Resting Pulse
You aren't stuck with the number you have today. The heart is a muscle, and you can train it.
- Zone 2 Cardio: This is the magic pill. It’s exercise where you can still hold a conversation. Think brisk walking or easy cycling. Doing this for 150 minutes a week strengthens the heart’s chambers, allowing them to fill with more blood and pump more efficiently.
- Magnesium and Potassium: These electrolytes are essential for the electrical signaling in your heart. Many people are deficient in magnesium, which can lead to "palpitations" or a slightly elevated resting pulse.
- Sleep Hygiene: Chronic sleep deprivation keeps your nervous system in a state of high alert. You’ll see your resting heart rate drop almost immediately after a few nights of 8-hour sleep.
- Vagus Nerve Stimulation: Simple deep breathing—inhaling for 4 seconds, holding for 4, and exhaling for 8—signals the vagus nerve to tell the heart to slow down. It’s like a manual override for your nervous system.
The Role of Wearables
We live in an age of data. Oura rings, Whoop straps, and Garmin watches are great, but they can also cause "orthosomnia"—anxiety about your health data that actually makes the data worse. If you’re obsessed with your heart rate, the stress of checking it can actually raise it.
Use the data as a broad-strokes tool. Look for the monthly average, not the minute-by-minute fluctuation. If your monthly average is trending down, you're doing great. If it spikes, check if you’re getting sick. Often, an elevated resting heart rate is the very first sign of a viral infection, appearing 24 to 48 hours before you even get a sniffle.
Actionable Steps for Better Heart Health
If you want to optimize your heart rate starting today, stop looking for a quick fix and focus on the biological fundamentals.
- Audit your stimulants. Switch to decaf after noon and see if your morning resting rate drops over the next week.
- Prioritize "boring" exercise. Everyone wants to do high-intensity intervals, but steady-state, low-intensity movement is what actually reconditions the heart muscle for a lower resting pulse.
- Hydrate with intent. Add a pinch of sea salt or an electrolyte powder to your water. Proper hydration reduces the mechanical workload on your heart significantly.
- Track your HRV. Heart Rate Variability is the variation in time between each heartbeat. A high HRV usually correlates with a healthy, low resting heart rate and indicates a resilient nervous system.
A healthy resting heart rate is a window into your overall longevity. It isn't just about avoiding a heart attack today; it's about ensuring your "engine" isn't running at max capacity when it should be idling. Keep the number low, keep the heart strong, and pay attention when the rhythm changes.
